Designing Ecological Habitats is the third volume in the Four Keys to Sustainable Communities series and is an important and eloquent exploration of humanity's limits to growth, addressing the problems arising from climate change, habitat destruction, population growth and resource depletion. This is not a book of theoretical ideas but an anthology of solutions, of experience, tried and tested, from experts all over the world. The designs and practices included in this book present a vision for the future, already tested out in eco-villages, sustainable communities and projects in many countries. These are practical low carbon solutions which provide significant improvements in the quality of life. Designing Ecological Habitats is an anthology of work by writers who have created, built, lived in and thrived in eco-developments, and addresses green building; food resources; appropriate technology; and restoring nature. The Four Keys represent the four dimensions of sustainable design—the Worldview, the Social, the Ecological and the Economic. This series is endorsed by UNESCO and is an official contribution to the UN Decade of Education for Sustainable Development.
